PROBLEM TO BE SOLVED: To narrow the clearance between flywheels to downsize a flywheel device for allowing each of a plurality of flywheels 3 that is relatively-rotatably and externally inserted into a wheel shaft 2 connected to a bearing ring to be connected to the wheel shaft via each clutch means 5.SOLUTION: Each clutch means 5 includes: an engaging hole 6 formed in each flywheel 3; a cylinder hole 7 formed in a wheel shaft 2; a pin 8 slidably engaged with the cylinder hole 7; and an oil passage 9 communicating with the cylinder hole 7. When a part of the pin 8 is pressed out of the wheel shaft 2 by the oil supply to the cylinder hole 7 via the oil passage 9 and is engaged with the engaging hole 6, the flywheel 3 is connected to the wheel shaft 2 via the pin 8. |
